refusal to stand behind manufactured product

My wife and I are on our 2cnd Oreck Vacuum machine purchased here in Honolulu.  The first one functioned pretty well and we had no real complaints.  The second one, however, has been a problem from the start.   When we first began using the machine it seemed very heavy and hard to push.  We took it to the dealer and were told there was nothing wrong with it, it must be our carpet.  So we took it home and tried again.  I called and questioned the dealer again and w as told the carpet must have a high humidity and that is making the machine hard to push.  So for nearly 2 years we have struggled with the  light weight easy-to-use Oreck and felt more and more that we should have returned it right away.  A few weeks ago we had the occasion to take the machine in to get a bag replacement and the technicians did some thing to the machine and when we brought it home it worked unbelievably w ell!

But, within 2 weeks it was back to the old push problems.  A gain we are told it is working properly.  It appears that the unit is not functioning with the belt properly.  The wooden roller has scorched and turned black on one end and the machine simply does not perform well at all.  

I am aware that we did not purchase this machine from your factory. Instead we purchased it from your authorized dealer.  Nowhere in your advertising do you advise clients to purchase from the factory in order to receive satisfactory customer service.  But that is the la test reason given us for your representative refusing to make good on your product.  I have attached the sequence of emails to date and am going to ask you a personal and very simple question.  Do you really back your products with pride and confidence? Or is the satisfaction guarantee phrase a platitude to create easier sales?  I find it hard to believe that a family proud company with the heritage you have in the community is willing to allow even one client clear over in Hawaii to conclude that Oreck cannot be counted on for integrity.

You will see from the email and the attached receipt that we simply  want our money back.  2 years of struggle is enough.  I wish the machine would work for us but am unwilling to undertake having a machine serviced every few weeks just to keep it operable.  I await your response.

The amount of dirt and dust that "got by" an Oreck is disgusting.
